Gel-wipe for personal care and household cleansing
View Patent ↗Gel-wipes suitable for use in personal care and household cleansing applications are disclosed, which include a substrate having a first surface, a second surface opposing the first surface and a body disposed between and defined by the first and second surfaces, fibers having an outer surface and an inner core, a polymeric gel distributed throughout the substrate such that a substantial portion of the fibers contain the polymeric gel distributed throughout the inner core of the fibers; and a liquid cleansing composition, wherein the inner core of a substantial portion of the fibers and the polymeric gel are substantially free of the liquid cleansing composition; as well as methods of making the gel-wipe.
1. A gel-wipe suitable for use in personal care and household cleansing applications, said gel-wipe comprising:
a substrate comprising fibers, said fibers comprising an outer surface and an inner core, said substrate comprising a first surface, a second surface opposing said first surface, and a body disposed between and defined by said first and second surfaces, said substrate comprising a polymeric gel distributed throughout said substrate and throughout said inner core of a substantial portion of said fibers; and
a liquid cleansing composition applied to said substrate in an amount effective to provide improved cleansing efficacy to said gel-wipe, wherein said inner core of said substantial portion of said fibers are substantially free of said liquid cleansing composition.
2. The gel-wipe of claim 1 wherein said substrate is selected from the group consisting of woven, non-woven and knitted fabrics.
3. The gel-wipe of claim 1 wherein said polymeric gel comprises a gelling polymer that has been reacted with a gelling agent to form said polymeric gel.
4. The gel-wipe of claim 3 wherein said gelling polymer is selected from the group consisting of sodium alginate, carboxymethylcellulose, guar gum and derivatives thereof, hydroxyethyl guar, carboxymethyl guar, methylguar, hydroxypropylmethyl guar, cationic guar, cationic hydrophobically modified guar, anionic hydrophobically modified guar, hydrophobically modified guar and borax; pectin gum, carrageenan gum; polyvinyl alcohol, cross linked polyacrylic acid, xanthan gum, gellan gum and ionic polymer or surfactant having a charge.
5. The gel-wipe of claim 1 wherein said polymeric gel comprises a cross linked polyacrylic acid.
6. The gel-wipe of claim 3 wherein said gelling agent is selected from the group consisting of Ca 2+ -containing salts, Al 3+ containing salts, K + containing salts; borax; neutralizing base solution of cross linked polyacrylic acid; divalent cations of xanthan gum, guar gum, and gellan gum, polymer or surfactant with an opposite charge of the ionic polymer or surfactant having a charge.
7. The gel-wipe of claim 6 wherein said gelling agent is a neutralizing base solution of cross linked polyacrylic acid.
8. The gel-wipe of claim 6 wherein said gelling agent is sodium hydroxide.
9. The gel-wipe of claim 1 wherein said liquid cleansing composition is substantially free of said polymeric gel.
10. The gel-wipe of claim 1 comprising from about 2 percent to about 50 percent of said liquid cleansing composition.
11. The gel-wipe of claim 1 comprising from about 4 percent to about 35 percent of said liquid cleansing composition.
12. The gel-wipe of claim 1 comprising from about 0.05 percent to about 5 percent by weight of said polymeric gel.
13. The gel-wipe of claim 1 wherein said substantial portion of fibers comprises at least 75 percent by weight of said fibers.
14. The gel-wipe of claim 1 wherein said substantial portion of fibers comprises at least 90 percent by weight of said fibers.
15. The gel-wipe of claim 1 wherein said polymeric gel is substantially free of said liquid cleansing composition.
16. The gel-wipe of claim 1 wherein said liquid cleansing composition is substantially free of a gelling polymer.
17. A method of making a gel-wipe suitable for use in personal care and household cleansing applications, the method comprising the ordered steps of:
providing a substrate comprising fibers, said fibers comprising an outer surface and an inner core, said substrate comprising a first surface, a second surface opposing said first surface, and a body disposed between and defined by said first and second surfaces;
contacting said substrate with a solution having a gelling polymer dissolved therein, under conditions effective to distribute said solution on said first and second surfaces of said substrate, throughout said body of said substrate, and throughout said inner core of a substantial portion of said fibers;
removing excess solution having the gelling polymer dissolved therein from said substrate;
contacting said substrate comprising said gelling polymer distributed there through with a gelling agent capable of providing a polymeric gel comprising said gelling polymer and then removing excess solution having the gelling agent dissolved therein from said substrate, thereby forming said polymeric gel distributed throughout said substrate, and throughout said inner core of said substantial portion of said fibers;
contacting said substrate comprising said polymeric gel distributed there through with a liquid cleansing composition; and
removing excess liquid cleansing composition from said substrate comprising said polymeric gel and said liquid cleansing composition; wherein said solution having said gelling polymer dissolved therein is substantially free of said liquid cleaning composition, and wherein said inner core of said substantial portion of fibers comprising said polymeric gel distributed there through is substantially free of said liquid cleansing composition.
